[0035] The working principle of this utility model is as follows:

[0036] This invention is suitable for use in continuous die forming of products with a negative angle of 5 to 10 degrees on a 200T equipment. Due to the limited equipment table space, and to save costs, this continuous die forming structure with a partial upper and lower double slider was developed: During production, the upper die part moves due to the downward movement of the stamping equipment table surface. When the upper die moves, the upper forming slider 9 is affected by the force of the lower nitrogen steel 11, and the upper forming slider 9 is drawn inward to the bottom of the stripper plate 7. The upper die part continues to move downward, and under the influence of the upper nitrogen steel 2, the lower die... The inner ejector descends to the lower die pressing plate (lower nitrogen steel 11 to the bottom), and the upper die continues to move to the entire die closing stroke (0 degrees to 180 degrees of the punch). The punch continues to move upward (180 degrees to 360 degrees). At this time, it is in the open state. After structural development, the lower die forming slider 16 forms the floating material, and the lower ejector plate 14 presses the material. When the stop punch 4 descends, it pushes the lower forming slider 16 to make a lateral movement, so that the negative angle of the part reaches the required negative 5 degree dimension, and the one-time negative angle forming can be completed.
